I was building this exhaust when I thought this was going to be a CMC car. My buddy said he'd weld for beer, and this was the end result. This was my first time building an exhaust so no need to tell me how amazing the work is. I already know.

It doesn't sound too bad around town. Needs a cat to mellow it out a little. That's a 3" straight through Borla muffler with obviously a stock at pipe and stock manifolds. I will say though, on the track at WOT it's bad ass. It's loud, sounds awesome, it pops, it bangs, and it shoots fire. I have people tracking me down to tell me how great it sounds. I'll take it.

Two problems. I need a cat relatively soon, and I'm getting too many fumes in the car. So I need to run the exhaust over the axle. I think the easier option is to replace the muffler with a high flow cat and use a stock over the axle exhaust pipe (I have one) and run the muffler straight out the right side of left side of I need the room.

Two quewtions.

1: how much hp will I loose? This is a bone stock LT1 with said exhaust and a Moroso intake.
2: wound it be worth it to get cheap eBay headers and Y pipe? Then I'd need two cats and a tune. But maybe it'll add enough hp to make it worth it?

I'm planing on switching to an LS1 soon. But at the same time this junk yard LT1 is running awesome. No smoke, burns maybe 1/2 quart of oil a day at the track and doesn't miss a beat. Kinda hard to justify spending the money when I have a perfectly happy engine. I'd rather put that money towards more track days.

Thoughts? Opinions? Good or bad, I want to hear (unless you're taking about my fab skills)!
