2013 1LE , looking to buy Long tubes
 

Hello all! First time starting a thread.
I’ve got a 2013 SS 1LE with NPP’s. I’m looking into getting TSP headers with HF cats. Do you guys know if there is a difference in “loud” with HF cats and off road pipes?

The cats will help kill a lot of smell and barely affect HP/TQ and sound. Once you go with the LTs the car will be way loud. The way I described it is the 20 y/o me loved it but the 40 y/o me went out and put the resonated X in to replace the H pipe. Still loud just not obnoxious.

If you're set on the TSP headers you're not making a bad decision but personally I went Afe (formerly Pfadt) and I really like them. The tuner was pleased with the extra TQ they made.

They're all an improvement over the stock manifolds.

What kind of resonated x pipe did you go with ? I’d really appreciate if you can show me an exhaust video ����

Is is it possible to go the LT and keep the noise low at the same time?
