Which Y pipe would you guys run with ebay headers? I need hi-flow cats with it.

Also, does the stock catback work with headers and a Ypipe? I don't want the car too loud.

I cant find any info, but how restrictive is the stock catback?

 

if you have ever looked under your car you would see a flattened tube from your left bank after the cat that and stock cats are restrictive.

 

I used a pacesetter Y-Pipe with my eBay headers. You COULD use the stock catback, but why? The stock diameter piping would hinder rather than help with your power gains. I'd do a search on LS1 Sounds and see what exhaust would fit you best.

 

Lsxtreme Performance on ebay makes one that fits. I have there headers and y and when i called in to place my order they told me told me they make one that fits the ebay headers too. As far as I know they are the only shop that makes a y-pipe that will fit the ebay stainless headers I wish they made it when i had the ebay headers on my car last year i had to pay a exhaust shop a 100 bones to mod mine and i already payed 175 for the y... BASTARDS lol. It doesnt look like they have any listings on ebay for it right now. If you want you can call them and talk to them 708-724-9545 this is the number i called to order mine. Hope this helps timmy..

 

Thanks man! Huge help.

 

Yeah TSP ist the one I got when I got the ebay headers last year I like the merge on it and with shipping it was like 175 but it has to be modified on the drivers side because it doesnt have tight enough bends to clear the floor with the china headers. But the exhaust shop got it to work for me by hacking the hell out of it LOL

 

How about these????

Any should work...LS1 y pipes seem to be pretty interchangable when it comes to long tubes..

 

Obx will only work with obx headers. Our y pipes are not interchangable. Like pacesetters will not work with arh headers. If you want to get a y pipe that works without modification then you have to buy one that is made for the headers. Every header companies collector points a little different. Tsp works with pacesetters and there own headers. Your best bet with any headers is to get a matching y pipe then **** just slaps together without having to modify enything or hack **** all to hell
