I haver the SLP LM right now. Im gettin the TPIS Long tube headers soon with no cats. obviously i cant run the loudmouth anymore cuz that would just be asking to get arrested (it would be straight off the motor)....what exhaust do you guys suggest for the TPIS LT Headers with no cats....I want it to be very powerful and have a deep rumble without being "obnoxious"....I was thinkin about goin to a custom exhaust place and getting a flowmaster put on with 40 series. Thanks!

 

how bout buying a chambered muffler from Summit and putting it in the Ipipe of the LM...that should give it a really nice tone and quiet it down a touch.

but if you ahve the $$ for the tpis Lts than why not just splurg on the GMMG exhaust...sounds awesome

 

I've been trying to get the TPIS headers, but I hear they're in backorder for about 4-5 weekes. Do you have any updates on how long until they're available?

I would recommend Borla for your exhaust, if you want a cool sound.

 

Im currently running TPiS long tubes with a 3" cutout and a series 80 flowmaster muffler. I've enjoyed the sound but I think I'm about to go with a dynamouth setup...

 

I ordered my TPiS LTs directly from TPiS.
They typically take about 6 weeks.
I welded in my own emissions fittings because testing is coming here in June. Had them coated locally here.
I put a Moroso spiral twister in the I pipe.
My car is as quiet as stock now. (I'm 45)
If you like it noisy but not painful a regular bullet in the I pipe will take the edge off but still keep the roar if you run a loud catback.
