I have a heads/cam/intake LS1 with headers, dual 3" exhaust with race bullets & turn downs. It sounds pretty bad *** right now, but I'm wondering if I could pick up a few more HP with an x pipe. Is it worth the $200 I'm going to spend at the exhaust shop? Thanks for any input!

So you just have pipes off the headers with no H, Y, or X pipe?

If you're happy with what you have I wouldn't bother with changing it.

Heads up to anyone and everyone! If you plan on EVER running a safety loop, there is NO way to run a full exhaust, X, H, or Y setup.

you need some sort of crossover pipe, X will get you acouple horse and H will give you a deeper tone

Not true. I run the lakewood safety loop on my car......

You don't need a crossover. You'd gain some decent low-mid rpm torque with an X/H merge along with a little decibel control.....along with a couple ponies up top, but nothing you'll feel SOTP. I don't run any merge on my swb, just straight 3" duals.

I am going to be fabbing up a H pipe setup on mine and I have a safety loop and tunnel mount TA

Yes, just 3" pipes running into bullets. The only way I would justify spending the money would be for at least 10 RWHP.

stop giving bad information.

I'm sure you know that cars in the 60's-70's with dual exhaust didn't run a merge.....and that tons of high powered track cars run either straight headers or mufflers right off the collectors right? I said you don't need one.....I didn't say you shouldn't run one. Like I said, you'll gain some decent low-midrange tq and a couple ponies up top from the improved scavenging......but running one absolutely ISN'T required.

This is true.

So is a 10 RWHP gain realistic by adding an x?

not unless you're pushing a crap load of power. I wouldnt if you are going to have to pay $200 to get it done

but if the OP doesn't want to get pulled over or get the wrong attention a crossover pipe helps with changing the tone, straight piping is just crazy loud

blue98Z

Yes and no on the straight pipes. If you run some decent mufflers that will fit and there are plenty that do, you can quiet it down a good bit. I've got the magnaflow bullets on my straight pipe setup and it's pretty tame compared to the LT/ LM setup I had before. I mean really tame until you get on it. Cruising at 80mph you can't hear the exhaust, just road noise from the tires, and in town 1st-4th it could probably be loud with an auto but not to terribly loud with the manuals. I like mine and will not go back.

i would run an x i have one on mine..... some of the cars that had duals back in "tha day" sounded like ***......

an H-pipe should be a lot cheaper to run than an x-pipe since you just have to run a pipe from one side to the other and not rerun them and bring them together for the x. i'd ask them how much an H would cost before you completely rule out the thought of running a crossover.
