Questions & Answers Ask a Product Question
Q:

Can you tell me if this model would work with my 2017 Dodge Challenger 3.6L?

Asked by JUSTIN on July 18, 2018

A:

This muffler is not recommended for the 2017 Dodge Challenger 3.6", a universal muffler would not provide a good sound on this car.

Q:

Would this product sound good on my 2009 g8 gt

Asked by BALDE on May 28, 2019

A:

Whether it sounds good or not on your car, or any car, is purely subjective. The only way to know is to find someone that has the same car as yours and has the same Borla mufflers, or buy them and try them out.

Answer This Question

Q:

I’m looking for an exhaust for a car my kid is building. It’s a 1983 toyota celica with a 2000 3SGE BEAMS engine in it. Would this be something that would work or are there other performance exhaust models to use?

Asked by NATHAN on December 01, 2019

A:

Very will built stainless muffler. Case is seam welded design with the end caps wire welded, the inlet and outlets are a true 3 inch. Which means no restrictions. This muffler is a straight thru design. It produces a Deep tone through the entire RPM range of your engine.
It will compliment any vehicle it is installed on.

Bought muffler because I didn't want any cruising drone. This muffler sounds great on acceleration and is quit while cruising down the freeway. Very pleased.

The mufflers were placed behind an LQ9 and they sound great! Low tone, good rumble, just loud enough to get noticed but not loud enough to be obnoxious. Did a lot of research before making this purchase and really happy with the decision.
