3in. thermal exhaust and 3in cat elim. downpipe owners

[2nd gen gst]

I'm wondering if anyone with this setup has sort of like a tractor sound when suddenly stepping on the gas. I guessing its because the cat has been removed and replaced by a staight thru downpipe. Could anyone else with this setup clairify this. WOT sounds insane

I have had the exhaust on my N/T for the last three years....Never noticed any tractor sounds....its a little raspy, but nothing I cant put up with

When my wastegate opens on my external dump people tell me that my car sounds like a "tractor" or a "mack truck" so yes I've heard that if you are talking about with an external dump dp.

It rumbles... and was very DEEP. The older thermals sounded better than the newer ones (I had an original model, non SS) It rusted and I broke it on a big launch. Now I sport a "Megan racing" ebay special. Looks nice, sounds like a pissed off car running lean with the straight pipe. I put in the high flow cat and it's pretty nice actually..

I don't have a o2 elim downpipe, only the cat elim downpipe with 3in thermal catback. I heard the tractor sound from outside watching a friend WOT my car. Thats why I was wondering if anyone else has the same tractor sound with this exhaust. But from inside the car, it sound great, you can't even hear the tractor noise. I think it may have a small leak somewhere. Oh yeah I put jb weld over the second O2 sensor as a temperary plug. I checked that and its still there, no holes burning through.

Note: this only happens on the first part of accelerating, when stepping on the gas, not all through accelerating. Thanks
