Exhaust with headers
I bought my 98 Z28 in october, and the guy threw in eldelbrock shorty bolt-up headers in with it, i was wondering what type of exhaust would sound really good with the headers hooked up, i was looking into offroad H and X pipes but im not sure if that would be way too loud, anybody have any ideas?
thanks - Kris

H and X pipes more even out the exhaust pressure from each bank on a true dual set up. I'm guessing you run emissions in WA so you're gonna keep the cat's on there to pass. I liked the Hooker cat back. Quiet with a lower rumble when idle but screams when you get on it.

Always been a fan of the Magnaflow systems. One of the first mods on our car was the installation of a catback. With, or without, cats these systems have a great sound.

I have Magnaflow on my car and really like the way it sounds. It's not obnoxiously loud, but it's not quiet, either. Sounds great coupled with a pair of long-tube headers, as well
Having said that, exhaust sounds are pretty subjective, and what sounds good to one person may not sound good to another. If you know anybody with an LS1 and an aftermarket exhaust system, go take a listen and see if you like what you hear, then find out what exhaust system they are running. Honestly, though, you really can't go wrong with a cat-back from any of the well-known exhaust manufacturers.2001 Chevy Camaro Z28 A4

Honestly you are better off selling those headers. The shorty headers will give you such minimal gain that it isn't even worth installing. Just bolt up a cat back to the factory Y, and when you want to do more, then go with long tubes.

I would use those headers to rest the box of longtube headers on in the garage while you install the longtubes. A lot of work to put those shorties in for basically no gains. If you're doing the work you might as well get some HP out of it. How much money do you have to spend on a catback? Are you looking for badass or mild mannered? GMMG makes the baddest ass exhaust I've ever heard on a f-body. You pay for it though.....$750.
Check out ls1sounds.com and listen to a few set ups.

For comparison sake, my understanding is that longtubes are generlly worth 20-25 hp together with an updated tune.

I believe you are right, and if there was an easier way to get it for the same or less money....

And, those shorties will hold you back in airflow when you decide to upgrade heads and intake. Then, you will need to install the LT's to get your full benefit.

I get your point AZ and agree, I'm just saying those of us who don't plan on or cant afford doing engine upgrades and continue to put bolt ons...it was just easy for me to change to shorties that bolted right in, unlike long tubes that require emissions changes to get rid of codes and clearance issues and new or no cats and new y pipe etc. He already has the shorties and I was just saying there not worthless and they are easy!!! They are by no means comparable to longtubes!!!

You planning on running cats though? Emissions won't pass you if you don't have them on the car.

Actually, since you're not cammed, you probably could pass the emissions test depending on how strict they are.
