my buddy said hes got a set of lt headers from a company called TPIS.. i know they make a good longtube for the vettes but have never heard anything for the fbody....anybody have any idea on their quality and fitment? thanks

 

i believe they are really into LT1s.

 

They were one of the first to modify modern EFI cars. A couple of my friends test fitted their LS1 LT's when they first came out about 4-5 years ago. Very nice quality.

 

TPI, LT1/LT4 and LSX TunedPortInductionSpecialties the first real EFI engine in the camaro/firebird/transam/corvette their the one's who make the big mouth manifold for the L98's and they also port LS6 02+ manifolds among many other things

LS1 Headers holy **** i didn't realize their headers are $700 . . . better design than SLP's though hahaha

 

Aren't they a sponsor? They take the LS6 mainfolds and cut off the snout and attach a 90mm opening.

They have TONS OF RACING EXPERIENCE! They started out with the good old TPI as said above. The Mini Ram ( See lt1) intake was an instant power gainer on the shitty long runner TPI intakes! There stuff is AWESOME QUALITY! I has a Set of TPI Vette Headers! Top Notch!

 

Yes I have heard of TPIS. Infact I have been to their shop. I bought a mock up block from a guy here who works at TPIS and he gave me a tour of the shop when I was there.Cant comment on the header fitment but I can say they are a well established and equipped shop .
He showed me their CNC machine and the parts they make as well as the engine dyno. In addition he showed me the process their headers go through before they are considered done.

I would be confident buying any of their parts.

 

is there any way to distinguish that they r in fact tpis headers cause another friend of mines tellin me they r jethots

 

I'm not sure if there is a way you can positively identify that it is indeed their header.You could call them and see if they can help you identify the headers.

 

I used them back in the day when I had my 377ci TPI motor. Good stuff.

 

What makes you say they have a bad design? I bet they have the biggest research facility out of all the aftermarket companies for these cars. Get your facts right first.

 

Myron Cottrell (TPIS) has been modifying EFI cars about as long as there have been EFI cars. Very reputable company.

 

i'm referring to SLP, they hang to low and there are proven numbers they don't flow as good as other in the same price range and just look at SLP's new desing compared to the old one definately not goin the same route with the collector that far down . . . so i'll stick with my statement

 

I know you were refering to SLP. They have no flow problems. They may hang lower, but that doesnt conflict with the effectiveness.

 

I have their longtubes, top notch quality and customer service.
