loud exhaust

greetings all, can you please help me. with my new exhaust dilemma IE "to loud" just got the car back from the performance shop. just had bassani stainless h pype with high flow cats and jba shortie headers and have slp loud mouths axle backs. I had the slp's on with the stock set up and sounded fine. still would like it loud but not this loud. any suggestions would be great. I don't want my neighbors killing me when I start my car at 5:30 am.

thanks again john

You have to change to a catted H-Pipe or different axleback setup. The SLP loudmoths are the loudest setup out there. I would try a different muffler setup.

I have the Stingers with my O/R bassani x-pipe and like it. It tried it with hi-flow cats and liked the tone, but I eventually got used to it and wanted it a little louder.

I'd say go either go back to the stock H or go back to the stock mufflers.

+1 can't go wrong with this direction.

From the clips I have heard, the LoudMouths sound like junk when they are with an offroad setup. They are super loud and just junky sounding. With a catted X or H pipe, they calm down and have a nice sound. I suggest going back to the stock H...or at least one with cats.

I'd say leave the headers and catted h-pipe and get some new mufflers.
I had slp with my setup and I didn't really like the sound then swithched to the frpp/stingers and they are perfect.

Ditto on the Stingers. The FRPP Stingers are loud, but not so loud that you're annoying. I wouldn't idle it for 20mins at 5 in the morning, but you get the picture.

Unfortunately the aftermarket mufflers everyone buys for the S197 make very little power gains so I say...

STOCK MUFFLERS back on! Won't cost you a dime

Speaking for myself, I didn't buy my mufflers for alleged hp gains. I'm not a ricer.

So buying mufflers for HP gains makes someone a ricer? I guess I was a ricer in my Z28 when I bought a my Borla system and gained 15 RWHP.

Mufflers. Stock or A/M, whichever you budget allows.

I think you would really be happy if you just switched out the muffler. Leave what you have, minus the slp. Check out those stingers too. I wish I had gotten them in the first place.

There's a marked improvement in throttle response with my Violators which I can feel when revmatching for downshifts.

You're probably joking, but I think to be a Ricer is to invest in "Show" before "Go." Sound = show. HP = Go. Ricers don't care about performance, they just want "cool" body kits and loud exhausts.

Now, if you're talking about the fast little Honda boys with full exhausts on their 4-bangers that actually result in a performance increase - those are import tuners. Ricers is a derogatory name used for people who invest in "Show before Go."

After reading my own mods, to date. I think I might actually resemble that remark Though, in my own defense... I don't have a body kit and my exhaust is anything but loud

Yeah, no offense. I hate on nobody - even ricers like you. (JK! ) I just have to make an annoying comment every time someone says "ricers" in the wrong context.
