Anyone running these..I have a 97 253 and am looking at adding them and have a couple installation questions for someone that might be running them..Surely someone is running them on a 253...

what ??'s do you have.. i do alot of high perf exhaust..

[happy]

some questions that may need to be addressed..

what engine , horse power, if its not stock what cam profile, and i believe i saw a question by you about dry exhaust... are you experiencing reversion??? or old manifolds that need to be changed..

and the final question.. what are your goals??? are you looking for hp gains??

you will also have to relocate your cables if they are on your stock manifold. I mounted mine on my transom. also call and talk to lighting mfg. tell them what you have before you order. there # is (951) 678-5631. you should notice substantial gain with what you have already done with your engine.
