What do u folks think I have a 99 Ta 383 tfs225 heads 102/102 intake and 1 7/8 headers. I'm torn between a free setup my friend has it is a 3 inch y pipe going into a 4inch pipe and single exiting out the back with a 5 inch Borla muffler or a 3 inch x pipe dumped before rearend with bullet style mufflers. Please give me some info so I wont loose power down low because of the lack of back pressure. What would be a optimal setup for me to make the most power

I wish I would've went true duals so that is what I would suggest,just dump them before the axle or run them under!! If you wanna spend alittle extra get the upper panhard bar from UMI an run them over the axle!!

You shouldn't lose any backpressure with anything after the y-pipe that is larger. In terms of power, the best set up would be the x-pipe. Each header would have it's own outlet. Depending on how much your going to spend on it though, the power drop using the free y-pipe set up from your friend may not be enough to justify buying a new exhaust, I'd spend that $$ elsewhere.

That of course is in terms of power. I know you didn't ask but if you want to go for sound, the x-pipe set up is a no brainer especially with the bullets (TSP anyone). Best sound around. If you want to go for looks, there is no way I would get an x-pipe dumped exhaust on my TA. Would look pretty dumb without the exhaust ports in the bumper filled in. Camaro's look ok, not Trans Am's

I just want the best performing exhaust on and off the nitrous. Ive had x pipes under rear end and dumped y pipes everything lol. Ive just never had this much power to deal with and am wantin to get the absolute most out of it

The dual setup will be the best power producing exhaust.

3inch pipes? With which mufflers?

Yeah I see what you mean. The x-pipe set up in terms of power will be best. The higher the hp, the higher the difference between the y and x set ups. Most people will say that a 3in can support over 1500hp, but you stated very clear you want to get the most out of it. That is the x-pipe.

Duals! I vote for an X Pipe (I've heard TSP's X Pipe is nice) and dynomax bullets dumped before the axle. Or if you want it to be a bit quieter but with a nicer tone, use powerstick mufflers dumped before the axle. Depends on if you want more of a raspy tone (bullets) or a a more deep tone (powersticks). Whichever muffler you get, make sure you go true dual... the Y pipe really chokes the LS1's :/ And on top of that the sound you get with duals is phenominal!

Backpressure is bad, you don't need any. Run the duals
