H-pipe conversion

What's the average price for an h-pipe conversion for my exhaust? And where can I get it gone.

The part, if bought online, is $140. To get someone to wield that in could be 50-100 more just in labor. Do you already have a cat back system?

you dont require an H pipe for the 3.8L due to its an even fire motor, you can use one but you dont have to. You can have someone cut off the Y pipe and just run a pipe on each side back. The issue is bolting/unbolting may not be possible unless they weld in flanges.

I'm running a pacesetter gt cat back conversion kit right now. It basically just keeps your cats intact and turns into an behind them for a gt cat back system. Again not a hole lot of performance but it sounds really good compared to the y pipe

yes tone will change along with a slight shift in the power band but you don't have to have any midpipe.

The pipe size after the cat is 2.5" and after t turns into a single exhaust it's 2.25 I believe

That would be awesome if you're right, because the cat back I have is 2.5" as well so all I need is 2.5" piping to stretch from the cats to the mufflers for a true dual exhaust ) then I search for a 4.2 to rebuild
