TSP headers?
 

Got an L99 and wondering anyone one here running TSP longtube headers and how was the fit and did you like the gains thanks

TSP 1 7/8 Headers for me were flawless, fit and finish.

Just ordered mine on Saturday knowing they were top notch. They shipped today. No problems with customer service either. No-brainer.

i have them and LOVE THEM

trans, what exhaust do you have? I put my JBA system in over the winter. Today is the first day I drove with BOTH windows down. I noticed some pretty rediculous reflections coming off houses. I'm really starting to think I'm going to need to drop some new mufflers in. I haven't installed the headers yet... still stock mids.

Do you "have to" get a tune for the headers???

Only have 3600 miles on the car. Was gonna do headers with the cats, and I already have a Airaid CAI.

You don't have to, but you should.

If you refuse to do it, get an ELM327 module and Torque Pro on your phone and clear your own exhaust-related CEL.

With that said, I'm pretty sure I would be running lean with a Fastlane intake and headers. Safest path is to tune.

TUNE IS A MUST..... and i have straight pipes on my car, loud as hell over 2000 rpm
i would not go with a can tune.. go to a local lsx shop and get it done.

Lol. Tune is not necessary. I assume that you don't drag every weekend so the occasional on ramp with no tune will be fine. Recommended sure, not a must by any means though.

Got these on my car and LOVE THEM. Order them now and never look back...

Just ordered the 2" LT's, and I cant wait to install...

Thanks for the feedback :) gonna order them ASAP!

I have them and I love them and they fit great.

Happy owner of these headers here :thumbsup:
