depends on what your building.plain carbon is a little easier to weld,but will rust right away unless you coat/paint it.

ive built many exhaust systems and used quite a few different mufflers including building my own.configuration of the system will also have a great bearing on the sound.as stated before what sounds good for a trip around the block may be unbearable after an hour or so.that being said if you plan...

any of the smaller isky mega cams would work.like the old 270 mega cut on a 106 lsa. 270* 221 @ 50 .465 lift 106 or 108 lsa.it would have a nice chop to the idle and probably run decent as well.

im with the idea of running a smaller cam,if it is mostly a street car.id rather have something with better "manners" street diving,and give up a little max et/mph at the track.but thats me.that being said id look at the old isky 280 mega.

id run the stock replacement hi comp pistons and the crane 278hmv or 278 powermax hyd cam.this cam has great manners and a powerband like a table top.specs are as follows : 278/290 duration 467/494 lift 114 lsa. crane lists the "basic rpm range" for the older hmv version at 2200-5800.i have...

rob,if you give jerry at schneider racing cams the spec he can make one for you at a fair price,if he already dont have one sitting around to copy.but ive never seen one off the shelf lol.i had the 340 auto cam in a warmed up 318.it ran ok,but not as well as i would have liked.i ended up...

magnaflow with an 18" body.or dynomax ultraflow ss (not the welded) with an 18" body.jones/full boar make a magnaflow copy for about half the price.thay are well made and also come in an 18" body.

first in line

they are just another flowmaster knock off.if you like the flowmaster type sound,but dont want the drone or rasp id suggest heartthrob velocity mufflers.chambered sound,high flow rate and no drone.

well put.from where i stand ive got some first hand know how on this subject.being a fabricator by trade ive built a few different exhausts for my car.if nothing else i can tell you this...that on my setup (street driven 340 with tunnel ram) there was a big difference between a 2.5 true dual...

for a chambered muffler my vote would be heartthrobs HVS muffler.very similar sound to a flowmaster...but they actually flow and they dont drone or resonate.or the classic chambered powersticks.for a straight thru design i like the jones thunderbolt glass packs combined with an x pipe (loud) or...

good read,but not apples to apples test.the h pipe system has chambered mufflers and the same pipe size front to back.the x uses "stepped"piping with 3.5 mid pipes and straight tru mufflers .a more accurate test would have been done with the same brand mufflers and system piping size for both tests.

bigger carb like a 750 would help.and ill throw in my 2 cents....isky 284 mega 284* 236@50 .505 lift 106 or 108 lsa. or schneider cams 284 solid...284* 240@50 .510 lift .014 lash 110 lsa.

on my setup an x-pipe made a noticeable difference in both sound and low end torque.top end felt the same,X,H,or true dual.but the x-pipe produced the best low end.the exhaust note also got smoother and quieter.

summit brand turbo muffler,dynomax super turbo or ultraflow.
