I am running JLT CAI with Dougs 93 Race tune (amazing) along with FRPP stingers.

What kind of power and seat of the pants impact would an off road H-pipe have on performance.

Thanks

From what I've read it's good for 8hp. Although after installing mine all I noticed was louder/better sound which made me feel like I was going faster.

Maybe 5 or 10 HP! ....but would definitely raise the volume of your exhaust note!

It will change the exhaust tone as stated above, but you will notice a very nice increase in power. You will probably need to use the end user adjustments, as removal of the cats will throw off your AFR a little bit. No biggie, its a very small adjustment.

Your Stingers will really come to life with the pipes offroad H. When I added mine, I gained 8 hp and about the same torque. Here's a quick video:

Really?

Before I bought mine I was sure to ask around online, as well as the person I bought my tune from (Bama) to see if anything needed to be changed if I got the O/R H and everyone said no as far as the tuning itself, except for turning off the rear O2 sensors.

Not knocking you or anything, I just wanted to make sure I heard correctly (or at least that's what I thought I was told ).

FWIW, on my car with my mods, a tune adjustment was not needed (didn't net me anymore power). But that's with a host of mods, maybe a different combo would need tweeked.

Emailed Doug With Bama And He Says No Retuning Req'd With The Off Road H Pipe

That's alright, I didn't take it that way! We just found here that with no cats changes the AFR approximately -1.5

So we bumped the fuel back up JUST a tad. Like I said, wasn't major... just used end user adjustability. Could be different between vehicles too? This happened on 2/3 with Pypes off road in particular.

I have the Pypes offroad H pipe and I'm having problems with it. Lots of people are complaining about how the flanges that hook up to the headers don't get tight enough and they rattle. Mine rattle like this too. I drove around with it for 9 months with flowmasters on and for obvious reasons, couldn't hear the rattle (or myself think for that matter). Now that it's winter, I put the stock muffs back on and I notice it right away. Pypes says the issue doesn't exist but it does.

It rattles because the header bolts are shoulder screws and only let the nuts tighten down so much before it bottoms out. Works good with the stock H pipe but the Pypes pipe needs more threads to be tightened.

I'm going to fix my rattle myself in the spring when I can get under my car. I'm going to buy new bolts and cut more threads on them with a die. That will fix it.

and yes my H section is welded, not clamped

I've read about people having this problem with the Pypes H. I've had mine for almost a year now and I've had it on and off about 1000 times doing miscellaneous things, and I've never had that problem at the manifold connection. Maybe they had a bad run of them???
