I made the numbers below with SLP 94/95 style headers, ORP/cutout, stock heads, hotcam kit and other boltons. I'm pretty happy with them. If you are getting SLP's definitely switch to the single cat style if you can, they are a much better design than SLP's d/c's.

I agree. The 94-95 SLP design is very different and better flowing than the 96-97 design. That is why I selected the 94-95 design.

Can you guys give us any 1/4 times or MPH gains with the header addition? I always like to compare real life numbers. Thanks

well guys, it was going to take the TPIS LT's over a month to get shipped out so i went ahead and ordered the AS&M's with the RT dual cat y-pipe (i got the last one RT has on their shelves; they discontinued it because of low sales). it's all suppose to be here by friday...and installed shortly after.

Any more comments on this?

If I could get SLP's for $450 coated is it worth getting LT's for $700 with the Y-pipe? (daily driver, not taken to track much)

I just put in my new TPiS Longtubes
They fixed the steering knuckle clearance problem.
We didn't have to hammer on any of the pipes.
Only had to trim the lip on the K member 1/8 inch
They come out level with the oilpan.
I had to wait about 6 weeks to get mine uncoated but for me it was worth the wait.
I welded in my own emissions fittings and had them coated here locally.
I couldn't be happier with them.

Dan, did you have any problem with Md VEIP and those LT's? I assume your running a single cat?

I'll try to scan them tomorrow afternoon at work. I have the before and after. Peak torque with the slp's was 306 at 3200 rpms.

I just finished my cam swap, and I would probably gain a bit more with LT's than with the shorties, but like i said, i'm lowered, so i can't do LT's.
Hey man, please post those graphs or at least put up the numbers every couple hundred RPM.
