Mufflers.

[GTP 40TH]

Anyone familiar with xlerator turbo mufflers put out by goerlich? Can purchase them locally for a pretty good price. Any feedback is welcome.

sounds like knockoff mufflers and they'd be cheap for a reason.

[TheOtherNick]

They are actually pretty decent mufflers, magnaflow knock offs, we carry them at work.

Thanks for the reply, They are made by goerlich. As I understand it goerlich is a very reputable company.

[TheOtherNick]

Yeah we have not had any issues with them,ive never put them on a gp tho.

I'd love to hear how they sound. My GP already has the resonator removed. Still has the stock mufflers in the back. I'm looking for a deeper sound. Think these will provide that?

[TheOtherNick]

Put a glass pack back in for a res, and they should sound exactly like magnaflows

Thanks for the advice. I had been considering trying a glasspack with the factory mufflers. I have a glasspack already. Think I should give it or go before trying the turbos.

Moved.

Installed the glasspack last nite. Sounds a lot better. Not near as raspy as before. I still plan to install the turbos over the weekend. Hopefully this will give me the sound I'm lookin' for.

More to come.

what glasspack did you install and if I went to a muffler place and said put this glasspack on my car what would it cost?

Regarding the OP question; I have used Goerlich XLerators on several cars over the years (my own and customer cars). I have only used them on '60s and '70s V8 applications.

They are VERY well built units with a deep tone. They flow much better than a turbo style muffler. They are a "straight-through" design, using a perforated stainless steel inner tube and densely packed (stainless steel and ceramic wool) case. They flow 96% to 99% of equivalent straight pipe flow rates.

Several videos on YouTube showing these on various cars, but primarily V8 muscle cars and late model trucks.

I know it doesn't help much, but here is a video of is how they sounded on my 71 GTO: YouTube - 71 GTO with Xlerator mufflers_0001.wmv

Very good info. Would love to hear these on a GTP. I am planning to try them soon. Decided against doing them this weekend. Will get done very soon. I really appreciate the input.

Quick update. Turbos installed. Could not be happier. Nice sound from these mufflers.

Less than $70.00 total. Installed them myself.

Thanks for everyone's input.
