Might be time to change the exhaust up a bit. I have a banged up TSP ORY pipe that I bottomed out a few times, plus it doesnt appear to be the best design. I also have PS 1 3/4 headers to LM1. Any suggestions.

Setup is prc 2.5 heads, 228 cam, full bolt on. Wondering what exhaust will work best.

How big is the LM1 after the merge?

Is it the newer TSP ORY that has the better merge?

MikeWS6

3" I believe.

Yes it is the 2010+ TSP ORY. So I guess you could call it "new".

Other than running a cutout, just having a good merge is about the best thing you can do here. How can you live with that LM1 lol? I had that before on my HCI setup, and it just drove me insane lol

i have KOOKS running through my OE SLP DD and it flows fine according to my dyno graph.


i would pick up some ARHs if i were you. you cant go wrong there.

So the new TSP ORY is not that bad? If its not ill wait til my pacesetters rust out then change out everything at the same time.

TSP 1 7/8" longtubes and TSP true duals

I was actually looking into this. My car has a pretty mild setup so I wasnt sure if the bigger headers / duals would be overkill.

What size is the merge on the TSP pipe?

MikeWS6

I think it's 3". It's loud but I usually have the radio on so I can't notice it.

Ideally you want a 3" going into a 4" for best results. If the outlet is truly only 3" that's no so ideal IMO....especially being that you have a HCI

So your saying theres prob another 5-10 in the Y pipe alone?

If it necks into a 3" pipe then yes there should be a few hp left on the table. If you weren't a head/cam car I wouldn't even care, but that car wants to breath now, and the small diameter outlet is probably choking it a little bit
