    which Borla muffler

    Ordered from Summit, the Dynomax welded Ultra Flow mufflers just arrived. The p/n that is a direct bolt in to replace the Super Turbos is #17219. Did some research on these, flow test results were posted on a Corvette forum and are impressive. Few other random comparisons were done by a...

    Finally: TTI's installed

    LOL, yea at the Mopar day up in Lebanon Valley. You dont want to know my reaction times, 'cause I prefer to forget them. I really should have gone to a normal Sat. test&tune to play first. I have had three unfortunate, but fun trips down the track to date. 1st run was my "hope it stays...

    Finally: TTI's installed

    Pretty mild. Original 340 block .030 over, stroked to 372. KB forged pistons, not sure if Mike used 10.5 or 11.0:1 pistons but he used a thick gasket to lower to 9.9:1. Custom UltraDyne Hyd. cam .500 Lift, and I think was 222-226 dur @ .050 or 224 -230 @ .050. LSA 112. I had to use the...

    which Borla muffler

    You are absolutely right, just returned from E Town today and got edumicated :) Met the dude with the beautiful green 70 'Cuda 440 (was a Viper color) had a complete tti 3" exhaust and the Dynomax Ultras. He introduced us to the guy who built the car, and he told us you can now get them...

    Finally: TTI's installed

    BTW, finally got my a$$ down for a full dyno tune. Carb tuning and timing needed attention, had no idea it was that far off. Picked up more than 30 additional peak HP, but I was more impressed with how the car reacts from part throttle and its overall acceleration gain from any RPM. He found...

    which Borla muffler

    For the TTI 2 1/2" exhaust to replace the dynomax that came with the kit. Obviously need the offset muffler, which the Borla does not force the spent gasses to swirl around the muffler like Dynomax. Has anyone swapped out the Dynomax for Borla's in their TTI exhaust, and if so what case size...

    Finally: TTI's installed

    Just wanted to add the p/n of the engine pipes since I've been getting request about them. A25RE and A25LE. Yes they are aluminized. Fits 67-76 A body. Can see them on the TTI website, they sell new for $178.00 pair. The flanges mount flush to the manifolds, as I had a request for the...

    Finally: TTI's installed

    Was beginning to believe I would never live long enough to see the day I finally purchased and installed them. Was using the original equipment '68-'70 manifolds on my stroked smallblock since spring '08. Ran them through brand new 2 1/2" tti exhaust system & dynomax. I knew those manifolds...

    TTI exhaust too loud

    tti, H-pipe & Dynomax mufflers. Sounds better than all my Harleys. Kinda wish it were louder! In all seriousness, the only noise that wears on me is that cruising drone @ 2000-2200 RPM. Dissapears when I stick my foot into it a bit more.

    Tech advice before doing TTI header install-

    OK, that doesnt look too bad at at all.

    Tech advice before doing TTI header install-

    I found those instructions at the TTI homepage and printed them off last weekend. Thats pretty cool they provide right on their website. I have access to a lift at a buddys shop if I need it -should make life easier. Im definitely VERY interested in what had to be done with the tranny lines...

    Tech advice before doing TTI header install-

    Need tech advice from those "who have installed these on A body" . Last time I installed headers was on E BODY, with LOTS of room. Will be installing the ceramic coated TTI's on my '70 Duster. Car has the 727 TF trans., and original 340 engine. No sheetmetal mods-all original body. (Already...

    factory flaw in a muffler?

    follow up: mufflers are OK. However my motor seems to hate the factory manifolds dispite the porting work done by Gesslers. Cant do it "this" year but the tti step headers are a must for a winter project. Might as well install the X pipe while we're under there. As soon as the new race...

    68-70 Hi po manifolds vs quality headers

    Hughes engineering also post results on their website: Two motors, stroker based on a 360 block and stroker based on factory 340 block. ALL stock iron ported and extrude honed. the 1st 360 test based 409 peak HP, 429.7 TQ with manifolds. Test 2 360 added the tti headers: 471.6 peak HP, 498...

    68-70 Hi po manifolds vs quality headers

    Yikes, basically 1.5 sec. in the 1/4 minus headers and slicks.

    considering Doug's

    Im wondering the same, just had a header conversation with Adam last night at Marcus. Seems like the price is right :) But I cant afford to gamble-already did with Dynamic converters.

    factory flaw in a muffler?

    Actually they are Dynomax Hi flow. The best performance mufflers they make. Apparently this extremely uncommon and Im having doubts the mufflers are an issue at all.

    factory flaw in a muffler?

    I have gone over the converter issues over in "transmissions". My engine builder reviewed in detail the motor specs with Dynamic to see what would work within my budget. They feel a 9 1/2" race converter is the cure-all, but told him the 11" street would work fine for me. Dynamic claims...

    factory flaw in a muffler?

    This must be a rarity. Has anyone ever been unfortunate enough to purchase a new muffler(s) that had an internal problem causing a substantial drop in performance? Im about to consider borrowing a pair of mufflers just to eliminate one component from the short list of what is ailing. I...

    68-70 Hi po manifolds vs quality headers

    Thats what my Mikey said, AND Jeff told me today. Mike designed a camshaft with the manifolds in mind to be a bit more forgiving. These suckers dont scavange well. Mike saw a little "black" inside the intake runners, potentially getting some reversion? Would have been worse with more...

    68-70 Hi po manifolds vs quality headers

    Like this topic hasnt been brought up before, LOL. Specifically, has anyone tried using them( factory manifolds) on a hi perf stroked smallblock street/strip application making between 400-500 hp. In your opinion-based on EXPERIENCE- do you feel it significantly hurt you with a solid "in the...

    And I thought TTI's were spendy

    Yikes that pricey. They do look exactly like mine from the pic except for the casting #'s missing. Now if they were PORTED manifolds, and came with the repro heat shields (which are also overpriced at I think $125?) it almost would be something to consider.

    Flowmasters for 2 1/2"

    I should note the mufflers have been long since sold. I still have parts from the tti 2 1/2" system we removed. The mid-pipes aka "H pipe", the tti mufler hangers (new) and tailpipe hanger recepticals (new). Fits all '67-76 A body small V8. For factory manifolds-not headers. Im selling this...

    Flowmasters for 2 1/2"

    Anyone need a pair of new Flowmasters for 2 1/2" pipes? They came on my car when I purchased it last year. Grand total of ZERO miles. We had to cut them off (welded on) and they can be spliced to fit over pipes again and clamped. I had these SOLD to a guy from Canada..but usps ground is...

    tti 2 1/2" from manifolds to mufflers

    Pic of the Flowmasters for sale. Still attached to the "first new" tti exhaust pipes that were installed on the car. The engine pipe pictured here is going to get trashed as they welded the whole thing up. Mufflers have NO miles on them, car was started & idled a few times, and I drove it up...

    tti 2 1/2" from manifolds to mufflers

    If I did this correctly (3) pics should upload of the tti exhaust engine pipe we will be removing from my Duster. One thing I forgot..and it a good thing... the exhaust is not welded so we can unassemble and ship in a box. It wil be oversized obviously but it's do-able. Pls note: I aint...

    tti 2 1/2" from manifolds to mufflers

    The engine pipe (still on car) has NO fitment issues anywhere. TTI is the best, after I install the headers I am going to purchase another headpipe from them. I am planning on getting the car on a lift NEXT Saturday to swap out the 8 3/4 gears so I could take a snapshot an email to you...

    tti 2 1/2" from manifolds to mufflers

    Im in Northwestern CT. @ 20 min from center of New Milford. 45 from Danbury.

    tti 2 1/2" from manifolds to mufflers

    Its just impossible to tell exactly how much it will cost as they are still on the car and not packaged up for shipment. Anything I tell you would just be a best "guesstimate" at this time. I remember the shipping from TTI wasnt overwhelming $$$ .
