Its louder than stock, but Very Tame. Too tame for me. I had a muffler delete and I liked that sound more than the XForce.

It's not bad at all. The volume is more and it gives you more of that aggressive tone that was put down with the stock exhaust. I got mine on sale at wheelwell.com last year for like $576 shipped to my door (non varex version). I like this exhaust and it's the best bang for your buck. I'm sure you'd like it too.

To me it is.. but the drone was unbearable for me and I rewelded the stock mufflers on. Otherwise, it sounded really good on throttle and on downshifts.

After seeing Val's post and talking with other members I finally decided to sell my JoeZ exhaust and install the Xforce Varex.
What really sold me is the fact the car will sound close to stock to keep my daughter, police, and neighbors happy. In that specific order of importance lol.

Summit has a great price still going and $30 off coupon bringing it to less than $1k shipped after taxes.

Hey guys, I have the varex exhaust coming in the mail any day now! Thanks to Josh at Meraki for providing!

Just a quick question, how many of the Bosal 256-287 gaskets should I buy if the Xforce provided ones are no good? Same goes for the 2.5" flange gaskets?

Did you use these at each connect point or just at the headers?

That type of gasket "donut" is for the header, the other connect points use the flange gaskets the kit comes with.

l'm considering installing the Xforce Varex myself this morning. I'll spray all the bolts and hangers with wd40. How hard could it be???

Has anyone experienced issues with install or any advice?

TIA

3-4 including myself had issue with passenger exhaust tip 1/2” long and needing cutting. Some had issues with center cross brace. I had a shop do mine.

Shop is currently installing right now and they've come across all the same issues as you mentioned, they said the quality was pretty bad . and its taking much longer to get it all to line up. They've spent hours on it $$$ and still not finished.

Can not believe they haven't rectified all of this by now, I mean they've been making these for the ISF for quite a few years now
