View Full Version : Off-road H-pipe

04-18-2012, 10:29 AM
thinking of going to an off-road H pipe, probably a BBK version? Presently, have upgraded the exhaust w/magna flow stainless mufflers. I'm looking for a little more of an old muscle car rumble. what so you think?
I've read varying hp increase from 2-3 to 5-10, any factual figures out there.

I like the idea a lot. You can go from 225 rwhp to 255 rwhp with a OR H pipe, cat back, cold air kit and a tune. You can get a few more ponies with an underdrive pulley system.

My friend gave me an X pipe with no cats and some equal length shorty headers. If I do the rest of the exhaust and a cold air kit could I see 265 rwhp? Do you need the tune with these mods?

If you want 260 rwhp, you're going to need a tune. I don't see you getting 265 but everything depends on how well your engine was built. Look for the 240 to 250 range. Put a set of AFR 185 heads on the car and you'll see 300's.

Thanks, at this point I just want to do some simple bolt on's. I have a track car I'm building so I want to keep the Cobra close to stock but I am going to use it has a stop gap until the track car is done so I can get some seat time in. So a little more power would be nice so I can try to keep up with some of the newer stangs.

Not to thread jack but what would you guys use for a cold air intake to go along with the H pipe on a 95 Cobra?
