    one of these days I'll get my car up in the air and put in an H or X pipe.....just haven't had the time and energy at the same time lately.......plus I HATE welding over my head lol

    I disagree. True duals with a crossover produce more power and torque accross the board than any other setup, including 4" y-pipe or even open headers.

    There's a reason all newer high performance cars come from the factory with true dual exhaust, its better than a Y system in every way.

    Hey WESMAN, Im from NJ too (central), I want to dyno my car while its stock to see where i start at and map my gains. Do you know of any good dyno places? CARTEK in Garwood is one...but back when they were still in their old shop they seemed WAY too busy. They now have a new place practically across the street, so maybe theyll have more room.

    i never said they were the best performing hands down. . . i said they were the best overall setup for these cars. ease of install and clearance is included in the "best all around setup". cant say anything on this whore without gettin your shit picked apart. but i always like what ya say wesman even if it is directed at me.

    Sorry I came accross that way, I mean it as a constructive objection.

    But as you said, they are definitely easier to install and less likely to sacrifice ground clearance.

    I've been very happy with my TD's, I had a shop do a custom setup over the axle, and its got about the same clearance as I had with my 3" Y-pipe. They haven't scraped the ground yet and they've been on there for 2 years. Of course my car is stock ride height as well.

    I highly reccommend Harris Speed Works. They are located in Warminster PA, which is right over the border in the outskirts of Philly. You're probably even closer to them than I am.

    I had my car dyno tuned there for a very reasonable price, and I was very happy with the service.

    Im curious, what kind of price is reasonable? Cartek was 500 for a dyno tune a few years ago (probably still the same).

    ah ok. 400 isnt bad. heres another question...do most catbacks flow about the same? I love the rumble of magnaflow, but someone said they didnt flow as well while I thought they performed quite well.

    magnaflow is a straight through muffler design with sound absorbing material not interfering with the flow. dyno tests with open header vs magnaflow showed like a 2 hp loss up top. borla is the same way. . . .except with borla you can bypass the muffler completely if you dont trust the dyno results. any chambered muffler impedes flow.

    Not true, Magnaflow performs just as well or better than many other catbacks.

    Its a 3" system with a straight-thru muffler. You can't ask for much less restrictive flow than that

    I thought it was a good muffler. I didnt know it was that good. Cool. My future setup haha:
    American Racing Headers with high flow cats
    Magnaflow cat-back
    LS6 heads (ported, polished, maybe valve job, i suppose milled too if I need it)
    228 cam
    Dyno Tune
    maybe an underdrive pulley to compliment it all

    when all is said and done I will be really close to 400 i hope

    If you mill your definatley over 400hp. And they have a flow rating for each catback it doesn't flow as well as hooker aerochamber but it's power you won't notice for the nice sound you get out of it.

    I have 3" true dual, x pipe, and dynomax bullet mufflers, and lowered 1.5 inches. I scrape every now and then, I cant believe a 4" would fit under there without scraping!

    i didnt realize miling would give such a bump, would milling be unsafe causing too much pressure? is it even necessary?

    Heres a great question: LS6 heads on ebay go for around $550 then Ill have to do some work to them. However, on ebay a nice set of 5.3L heads popped up for about $200. Is there a way to get the truck heads flowing like the LS6s after working on them?

    Im thinking theres no way, but I thought Id ask. I still want 243s.

    Worked 5.3's will never flow as well as 243's. The main goal w/ 5.3's is to max out compression 58cc 59cc to compensate for less flow. You know my stance on the issure so i'll throw you some links

    combustion chamber
    http://www.ls1tech.com/forums/advanc...ume-vs-cr.html
    And some head flow data
    http://www.ls1tech.com/forums/genera...ng-thread.html

    If you can afford to port and mill do both, if you want to save money then mill.

    no untouched casting flows as well as ls6 castings. . .however. . .between two similarly ported castings, ls1 heads actually outflow ls6 heads until mid-lift (.300-.350 range). and the increased flow of the ls6 after that lift range is minimal. . .so its up to you if its worth 500 additional dollars to get a set of ls6 heads, then get the work done to them. heres my stance on the issue : if youre not going to get aftermarket castings just use the heads you got and get them worked. . .if you are gonna buy a set of ls6 castings, then do work to them, you misewell get a set of dart heads for a couple hundred more than youd ultimatley spend porting ls6 castings and getting them milled.

    hmm, so many good decisions. but im only looking for minimum 400 rwhp. Ill keep searching for deals on heads. Im in no rush, just doing my research. Ill most likely do exhaust this summer to make room for the H/C's power.
